1. Discrete Electronic Circuits
To introduce the principles of circuit design using discrete transistors.
Understanding how transistors produce amplification. Why biasing is necessary. The
distinction between large-signal and small-signal performance. Analysis and exploration of a
range of typical circuit configurations. The factors affecting the frequency response of circuits.
How a conventional operational amplifier is structured. Open and closed loop analysis of
circuits including oscillators. The behaviour of MOS switching circuits.
The hybrid-pi model of field effect transistors. How to calculate circuit performance. Simple
single-transistor amplifier stages. The properties of Class A, B and AB amplifiers. The
differential amplifier. Active voltage and current biasing circuits. Design of oscillators.
Application of MOSFET as a simple switch and as a logic gate.
Ability to analyse and design transistor amplifier circuits, including their input and output
resistances, frequency response and dynamic behaviour. Analysis of DC coupled multi-stage
transistor circuits. Analysis and design of MOS and CMOS logic gates.
MOSET amplifiers: large and small signal models. Simple biasing arrangements.
Performance of common-source and source-follower circuits: voltage and current gain,
frequency response, Miller effect.
Analysis and design of DC coupled circuits. Advanced bias circuits - current mirror and
cascoding. The differential amplifier and its contribution to the op-amp. Complete op-amp
circuit. Common mode rejection ratio and effect of improved design. Sources of non-
linearity in amplifiers and impact on design. Oscillator theory and design.
Power amplifiers: Class A, B, and AB amplifiers and their application in op-amp, rf and audio
MOSFETs: I-V characteristics. Hybrid-pi model. MOSFET switching circuits.

These times are a rough estimate of the work required by a typical student. There will be
variations between individuals, but you will run the risk of failure if you spend significantly
less time on this course than these guidelines suggest.
